Title (EN) HOT RUNNER HAVING REDUCED VALVE-STEM DROOL
(FR) CANAL CHAUFFÉ PRÉSENTANT UNE COULURE DE TIGE DE SOUPAPE RÉDUITE
Abstract: front page image
(EN)Disclosed is a valve-gated hot-runner system (100; 200; 300; 400), having: (i) a back-up sealing arrangement (117), including: (i) a plurality of radial gaps (116A; 116B; 116C) associated with a valve stem (106) of a valve actuator (108), and (ii) a cooling system (114) being positioned relative to the plurality of radial gaps (116A; 116B; 116C), the cooling system (114) being configured to freeze a drool (109) being made to enter, under pressure, into the plurality of radial gaps (116A; 116B; 116C), so that the drool (109) that becomes frozen substantially reduces flow of the drool (109) along the valve stem (106) and toward the valve actuator (108).
(FR)L'invention concerne un système à canal chauffé à obturateur (100; 200; 300; 400), présentant (i) un agencement d'étanchéité de sécurité (117) qui comprend (i) une pluralité d'espaces radiaux (116A; 116B; 116C) associée à une tige de soupape (106) d'un actionneur de soupape (108), et (ii) un système de refroidissement (114) positionné relativement à la pluralité d'espaces radiaux (116A; 116B; 116C). Le système de refroidissement (114) est configuré de manière à geler une coulure (109) amenée à pénétrer, sous pression, dans la pluralité d'espaces radiaux (116A; 116B; 116C), de sorte que le gel de la coulure (109) permet de réduire sensiblement l'écoulement de la coulure (109) le long de la tige de soupape (106) et en direction de l'actionneur de soupape (108).
